Before processing, you must understand non standard parts
We know that precision machining can be divided into standard parts processing and non-standard parts processing according to the processing object. Relatively speaking, the processing of standard parts is relatively easy, while the processing of non-standard parts is relatively difficult.
1.Standard Parts
Standard parts refer to commonly used parts, such as threaded parts, rolling bearings, etc., which have been completely standardized in all aspects such as structure, size, drawing method, and marking, and are produced by professional factories. In a broad sense, it includes standardized fasteners, connecting parts, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts.
2.non standard parts
Non standard parts are other parts that are freely controlled by the enterprise except that the country has not set strict standard specifications and has no relevant parameter regulations. There are many varieties of non standard parts, and there is no very standardized classification at present. They are roughly classified as follows:
(1).Metal non standard parts
The customer provides the drawings, and the manufacturer uses the equipment to make the corresponding products according to the drawings. Non standard parts are usually mostly molds, and the tolerance requirements and finish are all specified by the customer, and there is no certain paradigm. Non standard parts require corresponding quality control from casting to finishing. The process is complex and variable, and the cost is generally higher than that of standard parts.
(2).non-metal non standard parts
Such as plastic, wood, stone, etc., in recent years, the injection molding industry. In recent years, in the injection molding industry, the development of plastic molds has become increasingly sophisticated, and the introduction of surface design and programming numerical control has greatly improved the cost and tolerance level of non-standard parts.
Our company can customize non standard parts in bulk. If you have any needs, please contact us.
